How to Flush a Radiator at Home

The best preventative maintenance item for any vehicle is its cooling system- the radiator. In order to maintain an engine, we mostly look out on changing engine well but forget about this. But keeping the cooling system in working order is also important. That is how learning how to flush a radiator at home is crucial. If you know the basic about it, chances are your car wills fewer visits in workshop and more in the road.

Learn How to Flush A Radiator at Home

Radiators can be extremely hot
and could severely burn if not handled carefully. So while working with that,
stay cautious every time. At first turn, the radiator off leave it off for a
few hours until it is completely cool.

Drain The Old Coolant

Locate the drain plug of the
radiator and drain the timeworn coolant inside of it. Park the car where the
coolant will not run onto the ground or drain if spilled accidentally. Thus it
collects deposits while running through the cooling system of the vehicle. This
is damage not only your engine but also the environment. Just make sure the
coolant is not hot. For opening the cap, you can use a rag to hold and unscrew
the cap.

Take some old towels or rugs
around the radiator to catch any dirty flowing water. Because once you remove
the radiator, it will flow out all the dirty liquid stored inside.

Take wide mouth container under
it to catch old coolant drain from the radiator. Use a screwdriver to open the
drain plug.

Add The Flush Product

After emptying close the drain
plug. Add the flush product and fill the remainder of the radiate with mixing
clear water. Tightly screw the radiator cap and start the car engine. Allow the
engine to run until the temp gauge shows the normal engine temp. Once they
reach the average engine temperature, turn the heater on and set the control
setting in highest fan and hottest temp settings.

Let the engine run in this
condition for 10 min. after 10 min off the engine and let it cool. When you
feel the radiator cap is cool enough to touch, you are ready for the next
drainage.

Drain The Flush Product From The Radiator

Now once again open the radiator
cap and drain the plug. Allow the flush product to let out fully. You should
collect the flush+ coolant combo reduces into a separate container. Coolant is
very toxic. If it falls into the ground, it will spread the toxin into the
soil, air, water which will affect your pets and children.

Refill The New Coolant

Now close the radiator plug very
tightly. Fill it with brand new antifreeze. Follow the instruction given into
the car manual for this. Of you can use premixed 50/50collant also. That
contains 50% antifreeze and 50% water.

Once the radiator is full, close
the radiator cap and run the car engine to check for any leakage.

Why You Need To Flush The Radiator

To keep the engine from damaging
you need a proper cooling system to keep the temp down. In the combustion
period, most of the energy produced by explosions. Which transfer into the
pistons and propel the vehicle. Like any system, the energy wastage is
occurring here also. And that can’t be converted into momentum. This waste
energy removed in heat form. If the cooling system is not able to remove this
heat, many dangerous incidents could happen. Even your car engine could be
blown up.

The vehicles engines and its
containing components are designed to operate under a particular temperature.
If that temperature range exceeds, the damage could happen. First of all, the
engine oil would be running outside of its temp range causing it to thin out
and not lubricating well. Second of all, the materials in the gaskets, seals,
etc. in your engine can start to break down — even the melts causing leaks. And
finally, the real metal in your engine will expand and pass it’s designed to
tolerances. That occurred wrapping and cracking which similarly cause leaks and
compression losing.

However, the cooling system of
maximum vehicles is always made with extra capacity. That ensures that it will
stay cold for the maximum time. But as the cooling system age and coolant
condition the ability of cooling of the engine get lower. In order to flush
your radiator and work of the cooling system, you will manage to keep the
entire operation in working form for a long time.

How Often You Should Flush

As you learned how to flush a radiator at home, you may wonder who often you should perform it. The smart way to learn about it to check the vehicles’ owner’s manual. Or you can ask your motor mechanic. He will suggest you about flushing schedule after judging the condition.

The common mistakes that car
owners make are to overlook the maintenance and care of the cooling system —
performing a proper radiator flush a crucial aspect of keeping the car well
maintained. Unfortunately, the only time a car owner thing of car cooling
system at the beginning of winter times or when the cooling system overheats
and start to giving them trouble. There is a small percent of owners check the
anti-freeze level during the winter months.

But if you take expert’s advice,
they will suggest you flush a radiator at least every other year to reduce the
build-up of deposits inside of it. Some of auto maintenance manuals suggest
flushing radiators in every 12 months.

Final Thoughts

If you have basic car maintenance
knowledge, you could try to flush your car radiator. Without knowledge of
primary engine and maintenance, this work should not perform at home. However,
you can expand your knowledge by learning from an expert (either your friend or
fellow mechanic) in practical. However, in case of an emergency, troubling
during flush the radiator at home doesn’t force anything and call for a
professional.
